HAND-RAKE.

SPECIFICATION formingpareof Letters Patent No. 563,923, dated July 14,1896.

Application filed September 4, 1895- Serial No. 561,430. (No model.) I

To aZZ whom it may concern;

Be it known that I, SAMUEL B. GUERNSEY, a citizen of the United States,residing at Corona, in the county of Queens and State of.

New York, have invented a new and useful Hand-Rake, of which thefollowing is a specification.

This invention relates to animprovement in hand-rakes and has for itsobject to simplify and improve the construction thereof and render thesame more durable and efiicient by providing a novel form of rake-toothmade from sheet metal and rolled into tubular form, said tooth beingformed in the process of manufacture with a hollow circumferentialshoulder which bears beneath the rake-head for limiting the upwardmovement of the tooth relativelyto the rake-head, and the upper end ofsaid tubular tooth being extendedthrough the rake-head and spreadagainst the top thereof to prevent the downward escape of the tooththrough its respective socket or perforation in the rake-head.

To this end the invention consists in certain novel features and detailsof construction, as hereinafter fully described, illustrated in thedrawings, and finally embodied in the claim.

,In the accompanying drawings, Figure 1 is a perspective view of arake-head, the teeth thereof being constructed in accordance with thisinvention. Fig. 2 is a vertical transverse section through the rake-headin line with one of the teeth. Fig. 3 is a detail perspective view ofone of the improved teeth.

Similar numerals of reference designate corresponding parts in theseveral figures of the drawings.

Referring to the drawings, 1 designates the rake-head or wooden bar towhich the teeth are to be applied. This rake-head, it will beunderstood, is connected with the usual rakehandle and braced relativelythereto by means of the usual diagonal rods, or in any other ordinary orpreferred manner, and said rake-head is also formed with a series ofvertical openings 2, into which are fitted the upsheet-metal blank ispassed between suitable rollers and shaped into the tubular formillustrated inFig. 3. During this operation, or in some previousoperation, if preferred, each tubular tooth is formed with an annularridge or corrugation 4, which when the tooth is in place is adapted torest beneath and against the lower face or edge of the rake head or bar1, and thereby limit the upward movement of the rake-tooth relatively tosaid head. Each rake-tooth is also made of sufficient vertical extent topass entirely through the rake-head 1 and project slightly above thesame, and that portion which projects above the rake-head is splitlongitudinally at numerous intervals. After the tooth is pushed upwardlyas far as the annular ridge or shoulder 4 will permit, the separatedportions 5, included between the incisions in the upper extremity of thetooth,are spread or defiected radially and clenched against or partiallyembedded 'in the upper edge or face of the rake-head in the mannerillustrated in the drawings, and this effectually prevents the downwardwithdrawal or escape of the tooth. In the application of theteethto therake-head, the seams 6 of the teeth are preferably disposed rearwardly.

The construction above described afiords a very light, durable, andeificient rake-tooth which may be readily applied to the rakehead andsecured firmly in place. The annular ridge or shoulder 4 and the splitand radially-spread upper extemity of the tooth regulate its positionwith regard to the rakehead, and the entire tooth is capable of beingrolled quickly into shape, thus rendering the tooth inexpensive inmanufacture.

It will be understood that the teeth maybe made-of any desired length ordiameter and spaced any desired distance apart upon the rake-head andthat other changes in the form,

proportion, and minor details of construction may be resorted to withoutdeparting from the spirit or sacrificing any of the advantages of thisinvention.

Having thus fully described the invention, what is claimed as new, anddesired to be secured by Letters Patent, is
